I looked through all the threads debating between deltas and Q-500 type planes and it seems like the worst thing about deltas is the "wetted" surface, which I don't really know what that is but I think it has something to do with it having a longer chord and the air touching it longer?
I was just wondering if anyone ever built one like this (Da-Wing) "

Just wondering,
